LOCOMOTIVE-JOURNAL-BOX MOUNTING.

Specification of Letters Patent.

Patented Mar. 26, 1918.

Application filed July 13, 1917. Serial No. 180,438.

To all whom it may concern Be it known that 1, ROBERT E. MAXWELL, a citizen of the United States, residing at Savannah, in the county of Chatham and State of Georgia, have invented certain new and useful Improvements in Locomotive- JournaLBox Mountings, of which the following is a specification.

This invention relates to locomotive journal box mountings, and has for one of its important objects to prevent looseness of certain parts of the mounting and to effect adjustments thereof to take up wear.

It is a common practice to employ flanged shoes in the journal box opening, one shoe embracing one of the pedestals and the other shoe embracing the other pedestal. These shoes are loose when originally put in place, and by reason of vibration, they wear the pedestals. It is an important object of this invention to prevent this looseness and thereby to prevent wear upon the pedestals. To accomplish this-result, I provide a wedge member mounted in a groove in the inner face of one of the flanges of each shoe, and I mount the wedge on the binder and provide for convenient adjustment of the wedge to take up wear;

As a general practice, the connection between the wedge shoe and the adjustable bolt has been a loose connection, and while the bolt itself may be rigid with the binder, the wedge is loose thereon and therefore capable of shaking under vibrations of the journal box, resulting in wear upon the wedge and the frame to such an extent that frequent adjustments and renewals of the wedge are necessitated. According to the present invention,I preserve a detachable connection between the bolt and the wedgeshoe, while at the same time I also maintain a rigid connection between the adjusting bolt and the wedgeshoe when the latter has been set to any adjusted position.

With these and other objects in view, the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described, shown in the drawings, and particularly set forth in the appended claims, it being understood that changes in the form, proportion, size and minor details may be made within the scope of the claims, without departing from the spirit or sacrificing any of the advantages of the invention.

Like characters of .reference designate corresponding parts in each of the figures of the drawings.

In Figs. 1 and 2.0f the drawings, there have been shown the usual pedestals 1 and 2 of the journal box frame of a locomotive, and the binder 3 suitably secured across the lower ends of the pedestals, say for instance by suitable fastenings 4 in the form of bolts extending through the binder and the lower portion of the frame. The pedestals 1 and 2, the binder 3 and the upper horizontal member 5 of the frame define an opening 6 for the reception of a journal box in the usual manner. At one side of the journal box opening 6 there is a. flanged shoe 7, said shoe embracing the pedestal 1 which has a substantially vertical inner face, while a flanged wedge-shoe 8 embraces the inner face of the pedestal 2, which face is inclined upwardly and inwardly, as at 9. The parts thus far described are old and well known and form in themselves no part of the present invention.

One of the features of the present invention is to prevent transverse looseness of the shoes, and this is accomplished by means of an upstanding wedge 10, one for each shoe. Said wedge is received within an upright groove or channel 11 formed in the inner face of one of the flanges of each shoe. By reference to Fig. 5 of the drawings, it will be noted that the groove 11 is deepest at its lower end and tapers in depth upwardly. The wedge 10 has its outer face, or that face which engages the pedestal, straight and vertical so as to lie against the face of the pedestal, while the inner face of the wedge is inclined in accordance With. the inclination of the back wall of the groove or channel 11 in the flange of the shoe. The wedge is longer than the shoe and projects clownwardly through the open bottom of. the groove 11 and has its lower end adjustably secured to a bracket 12 provided upon the adjacent upright face of the binder 3. While any form of bracket and adjustable connec tion with the wedge may be employed, a satisfactory form of bracket is that of an arch, as shown in Fig, 3 of the drawings, the opposite ends of the arch portion being formed into ears which are secured to the binder 3 by suitable fastcnings 13. The lower end of the wedge 10 is received between the arch portion of the bracket and the adjacent face of the binder, and a set screw 14 extends through a horizontal slot in the binder and engages the wedge or with one of a series of openings 16 in the lower end por tion of the wedge. By this arrangement, the wedge may be driven upwardly until the shoe is rigid in a lateral direction and then the set screw 15L may be tightened to hold the wedge in its adjusted position. The wedge is, of course, positioned after the shoe has been put in place and is driven upwardly through the open lower end of the groove 10, having first been introduced upwardly between the arch portion of the bracket and the adjacent side of the binder 3.

It will, of course, be understood that the construction and arrangement of the lateral wedge for the shoe 7 is exactly the same as for the wedge-shoe 8.

The wedge-shoe 8 has its inner upright face inclined with the inclination of the face 9 of the pedestal 2, and the flanges of the wedge-shoe embrace the pedestal in the usual manner, as clearly shown in Fig. 2 of'the drawings.

For the purpose of adjusting the wedgeshoe vertically, there is employed a wedgebolt 17 which passes loosely through a vertical opening 18 in the binder 3 and has its lower threaded end portion received through an arched or yoke-shaped bracket 19 secured a to the underside of the binder 3. An upper nut 20 and a lower nut 21 are provided upon the lower threaded portion of the bolt 17 and at opposite sides of the bracket 19, so that by manipulation of the nuts 20 and 21, the bolt may be adjusted vertically in opposite directions and thereafter held rigidly npon'the bracket by setting the nuts tightly against opposite sides of the bracket. The lower extremity 22 of the bolt is made polygonal so as to form a wrench-head. The upper threaded end of the bolt is received within a bifurcation in the lower end of the wedge-shoe, said bifurcation consisting of a throat portion 28 opening through the bottom of the wedge-shoe and a larger seat portl0I1'241; Within the seat portion 24 there'is a nut 25, and the upper threaded end of the bolt 17 is engaged with this nut. By rotating the bolt 17, through the instrumentality of a wrench applied to the lower end of the bolt, said bolt may be turned within the nut 25 until the upper extremity of the bolt wedge-shoe 8, as the vertical adjustment of the wedge-shoe is obtained through the nuts 20 and 21. By this means, the bolt 17 may be rigidly supported upon the binder, and

the'wedge-shoe 8' rigidly supported upon the.

bolt, whereby there will be no looseness between the wedge-shoe and the bolt, thus obviating the wear incident to such loosenes's.

l-laving thus described the invention, what I claim is:- r i r 1. A shoe for journal box pedestals comprising a back having a longitudinal flange,

said flange having a longitudinal groove or channel in the inner face thereof, and a wedge-member adjustable longitudinally in said groove or channel.
